The one that started it all: Our most-loved, best-selling sleep bag. A wearable blanket that helps baby fall asleep (and stay asleep), so you’re not up all night. Designed to be safe sleep, diaper change friendly, temperature-regulating, and so soft you’ll have to touch it to believe it.
- Exterior: 97% Bamboo Rayon, 3% Spandex
- Filling: 100% Polyester
- Highly breathable
- J-shaped double zipper
Due to lack of quilting the 0.5 TOG Sleep Bag tends to run bigger and have more stretch. We recommend following our fit guide/rules found in the blog here to determine if it is the correct fit.

Sleep Bags from Left to Right
XS, S, M, L, XLHere is a couple things to note before your purchase:
- As of Fall 2020 we began the process of transitioning our inventory from having tags at the neck to having that same information printed on the garment. We are unable to guarantee which version you receive as it depends on how quickly inventory sells through. As we want you to love every piece of Kyte BABY you receive please contact info@kytebaby.com for any questions or concerns once your order arrives.
- Our most recent batch of 2.5 TOG items are more compressed than previous productions. These products are not defective and are the same weight/warmth as all 2.5 TOGs. They may, however, feel thinner or slightly different than previous batches, due to this compression difference.
- As of Fall 2021 we began adding fold-over mittens in sizes Preemie to 0-3 months on some of our long sleeve apparel. In an effort to reduce waste we will continue to sell the original versions without the fold-over mittens. We are unable to guarantee which version you receive as it depends on how quickly inventory sells through. As we want you to love every piece of Kyte BABY you receive please contact info@kytebaby.com for any questions or concerns once your order arrives.
-Colors may vary from how they appear on computer/smartphone screen.
- We succeeded in creating the softest possible fabric for your little ones, and we do our best to preserve that same softness on our prints. Due to the nature of the printing process, our prints have a slightly different feel. The rule of thumb to follow is: the less printing there is, the softer the fabric will be. If you are disappointed with the items, please don’t hesitate to let us know, and we will gladly create an exchange or return for you.

What TOG do you need?
TOG is a rating system that measures warmth and calculates how quickly a fabric uses heat. It is the standard when choosing the appropriate sleeping bag for your baby, depending on the ambient temperature in your nursery. We recommend a heavier TOG during cooler months and a lighter one during warmer months.
This sleep bag is a 0.5 TOG, perfect for 23 to 26 °C or 74 to 78 °F.
Shop this style in: TOG 0.5 , TOG 1.0 or TOG 2.5.
The Kyte Baby Standard
Never not innovating
We’ve been researching, developing and innovating our sleep bags since 2014. We’ve set the standard for the softest fabric, the most user-friendly zipper design, the most durable stitching, and the safest, most comfortable design on the market—and we’re not stopping there.
We’ve expanded our sleep bags to include four sizes in three different weights, three sizes of sleep bag walkers, and a newborn sleep bag—the first of its kind in the market. Because we believe as long as the needs for safe and comfortable sleep keep changing, our products should, too.
